IMPROVEMENT IN KNIFE-POLISHERS.

To all whom it may concern:

Be it known that I, WILLIAM H. OmvnvrrNes, of Oxford, in the county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Knife-Polishers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing which forms a part of this specification, and in which- Figure 1 represents a perspective view of my improved knife-polisher. Fig. 2 represents a central longitudinal section of the same at line A B, Fig. 3; and Fig. 3 represents an end view of the polisher.

The nature of my invention consists in certain improvements in devices for polishing knives and other similar articles.

My improved knife-polisher is composed of a short cylindrical tube or receptacle, A, having inserted in each of its ends a cork head or plug, B. The heads B are faced upon their outer end with leather disks 0, perforated at their centers, and passages or openings D are formed through the centers of the heads B, which passages lead from the interior of the receptacle A to the outlet-apertures in the disks. Small patches of cloth or paper E are pasted over the openings in the disks, and the interior F of the cylinder or receptacle is filled with emery-flour or some other suitable material in a pulverized state. In this condition the .polishers are ready for market.

When the polisher is to be used the patch E should be removed from the orifice in the facingdisk 0 at one end of the polisher, and the knife to be polished should be held upon a board, plate, or some flat support sufficiently broad to catch the escaping dust. The polisher is then rubbed back and forth with the face-disk pressed firmly down upon the knife, and the emery-flour dropping through the opening D keeps a constant supply of the material between the disk 0 and the knife, so that a fine and brilliant polish is quickly produced. When all of the emery-flour or polishing-material has escaped from the cylinder A one of the heads B can be removed and the cylinder refilled with fresh material; or the same material may be collected and returned to the cylinder. The tube or receptacle A is, in this instance, made of tin and in cylindrical form; but any other suitable material may be used therefor, and the form thereof may be somewhat varied. Other materials besides cork and leather may be used in the construction of the heads B and their flanges D, but I prefer the construction and materials as shown and herein described.

What I claim, and desire to secure by Letters Patent, is

A knife-polisher, consisting of the cylinder A, closedat each end by a perforated plug, B, with or without a facing, G, as herein shown and described.
